To all whom it may concern:

Be it known that I, KARL H. Prnson, a subject of the Emperor of Austria,and a resident of New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain; new 7 and useful Improvements inAeroplanes, of which the following is a specification.

My invention relates to air and water 0 navigating vessels chiefly ofthe heavier than air type provided with sustaining planes, and among themain objects thereof are to provide a hull of boat 'form which iswaterproof and may be made air-tight, which is provided with a pluralityof independently operated propellers arranged in sets on opposite sidesthereof and each bf which is on a mount which may be rotated on ahorizontal axis transversely of the hull whereby the positions of thepropellers may be altered at will to propel the vessel in the air or .inwater, to turn the vessel in a circle of very short radius, to turn thevessel on its vertioalaxis, toinstantly stop the vessel,

and to hold the vesselmotionless in the air.

My invention isfully described in the following specification, of whichthe accompanying drawings form a part, in which like characters refer tolike parts in each of so the views, and in which:-

Figure 1 is'a side'elevation of an aeroplaneconstructed in accordancewith my invention;

' Fig.2 is a plan view thereof, with the 85 planes partly broken away;

i Fig. 3 IS a section taken on the line 3 -3 0f'Fig.1';- v

- Fig. 4 is a section taken on the line 4-4 of Fig. 3; and' v Fig 5 is asection taken on the line'5 5 of Fig.4., p

Referrin to the drawings, 6 represents the hull o boat. shape with thestem and stern of similar formation, a lower deck 7 being providedserving asa support; for a.

plurality of motors 8 and forming a storage space 9 thereunderfor fuel,water, oil, or-

other materials, and an upper deck 10 may be provided, and preferablywill be, for protecting the interior of-the hull against the admissionof water and, if desired of air as at. high altitudes in which event t eoccupants of the vessel will beprovided with air stored in compressedform in suitable containers.

The vessel is provided with masts 11 for rudders 14, and I prefer toform the deck' 10 on an arc of a circle to serve as a stabilizer, and toprevent the vessel from turnm over.

ecured to the .sides of the hull, in the positions of the motors 8, arerecessed plates 15 to-which annular recessed plates 16 are bolted, eachrecess serving for the rece tion of a ring 17 the inner periphery ofWlllCh is toothed at 18 to' form an internal gear, suitable racew'aysbeing provided for ball bearings 19 and 20 whereby said ring may revolvein an anti-frictional manner by means of a pinion 21 on a shaft 22provided with a hand wheel 23 interiorly of the hull 6.

Bolted or otherwise secured to the ring 17 in each recess in a conicalcasing 24 which carries a gear case 25 at its outer end for gears 26 and27 secured toa drive shaft 28 and a stub shaft 29', respectively, thefol;- mer of which carries pulleys 30 at its inner end connected withthe respective motor by means of a belt 31, andthe latter of whichcarries apropeller 32 arranged slightly out of parallelism with thedrive shaft 28, as is clearly shown in Figs. 2 and 4.

From the foregoing it will be seen that each propeller ha'sits own motorand may, therefore, be independently operated and each casing 24: may berotated to revolve the propeller carried thereby around its drive holdthe vessel motionless in the air, the pro-v pellers bein swung abouttheir pivots 2 8 by means 0 the respective hand wheels 23 intoproperpositions toaccomplish the desired result. v

The head casings 25 are. made leak proof whereby any suitable lubricantmay be cantained therein and the conical casings 24 are also madewaterproof whereby no water may enter thehull through thelpropellermounts;

My aeroplane is well ada ted for long flights, such as across oceans,ecause of the adaptability to meet varying conditions and of the greatcapacityhfor stores, and the vessel maybe navigated in the sea as wellvas in the air, utilizing the same meansof propulsion in each case 21nd,.in thi's'connection,

I will only utilize apart of the propeller battery in straightawaysailing, reserving the balance for emergencies whiclrmight arise, thelocation of the propellers rendcr-' ingw each as efficient as anotherand, when the propellers are set at a proper angle,'they serve as an aidinarising from the ground.

or water although the horizontal rudders 13 will be used for thispurpose in the usual manner.

The shape of the hull offers little resist ance to air' or water and myvessel is. therefore capable of high speed as well as providing maximumcomfort to the crew and assengers, if the latter are carried and, in theevent of damage to the planes 12, the propellers may be swung so astosustain the vessel in the {air and to control the descent Without theneed-for volplaning.

My invention is very simple, entirely practical," easily controlled, andcomparatively inexpensive, and it may be,made of great size to serve aspublic carriers, either for I freight or passengers, or both.

While I have shown a preferred embodiment of the invention, it will beobvious that I may make structural changes thereover, provided that suchchanges do notdepart from the spirit. of the invention and come withinthe scope"o f the appended claims.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A self propelled conveyance comprising a water-tight boat shapedhull, sustaining driving shaft. extending along the axis of each casing,a propeller axle journaled in the outer end of the casing at an obliqueangle to the driving shaft, connections between the two shafts, means torotate said shafts and propeller from within the hull, and means torotate the several casings around'the axes of the driving shafts thereinso as to revolve the propellers around the axes of said driving shafts.

2. A self propelled conveyance comprisaasaeea ing planes, rudders, aplurality of watertight casings along each side of said hull, means torotate the several casings, and an independently operated propellercarried by each casing.

3. An aeroplane, consisting ofa boat shaped hull, sustaining planes,rudders, a plurality of recessed plates along each side of said hull, aring rovided with a casing revoluble in .each p ate, an independentlyoperated propeller carried by each casing,

and means interiorly of said hull for revolving said ring to revolve itspropeller about a horizontal axis arranged transversely of said hull.

4. An aeroplane, consisting of a hull g sustaining planes, rudders, aplurality of recessed plates arranged along each side of said hull, aring provided with an internal gear revoluble in each plate, a pinionenmeshed with each gear, a shaft for said pinion extended into saidhull, a hand wheel stub shaft journaled in said gear case, a

gear thereon enmeshed with saiddrive shaft gear, and a propeller on saidstubshaft.

6. An aeroplane, consisting of a hull, sustaining planes, rudders, aplurality of rotatable casings on each side of said hull, meansinteriorly of said hull for operatin saidcasings, a gear case on theouter en of each casing, a drive shaft in each casing, a motor therefor,a gear on the outer end thereof, a stub shaft arranged at an obtuseangle to the axis of said drive shaft, a'gear thereon enmeshed with saiddrive shaft gear,

and a propeller'on said stub shaft arranged at an acuate angle to theaxis of said drive shaft.
